使用 Python 中 BeautifulSoup 的特定样式获取所有标签

Question

我正在尝试解析一些 HTML 文件。我想使用特定的字体大小提取所有文本。例如，我想以他们的风格使用font-size:10px 获取p、div、span 等标签的所有文本。我正在使用 BeautifulSoup 来解析我的 HTML 文件并提取首选数据。为了使用特定字体大小提取标签数据，我在 python 中使用了以下脚本。虽然它不起作用。

file = open("file.html", "r")
soup = BeautifulSoup(file.read(), features="html.parser")
main_texts = soup.findAll(attrs={"style":"font-size:10px"})
for item in main_texts :
   whole_text += item.getText()

另外，我的 HTML 内容是这样的

<span style="font-family: TimesNewRomanPSMT; font-size:10px">   </span><span style="font-family: ABCDEE+Calibri-Bold; font-size:11px"> </span><span style="font-family: TimesNewRomanPSMT; font-size:14px">Academic Qualifications <span style="position:absolute; border: black 1px solid; left:36px; top:143px; width:159px; height:0px;"></span>

你有什么办法解决这个问题吗？

Answer 1

您可以使用[attribute*="value"] CSS 选择器。

要使用 CSS 选择器，而不是 .find_all() 方法，请使用 .select()：

...
# The following will select all `style` elements containing `font-size:10px`
main_text = soup.select('[style*="font-size:10px"]')
